Supply of electric power control unit 117 determines the position of light source switching part 118 based on the detection signal of input, and selects to want
The light source switched on and off and the fan to drive and stop by the supply in supply of electric power portion 116.It should be noted that supply of electric power
Control unit 117 can control the on and off of light source as analog circuit.
Fig. 3 is the schematic diagram for the configuration for showing light supply apparatus shown in Fig. 1, and shows by being used as assisting
The case where light that the second light source 113 of light source emits is by as illumination light emitting.When light source switching part 118 is from as shown in Figure 2
When the state movement that the illumination light that first light source 112 emits enters, which is switched to second light source 113 as shown in Figure 3
The state that the illumination light of transmitting enters.For example, light source switching part 118 can be realized by mobile operating bar 100 (referring to Fig. 1)
This moving operation.It should be noted that light source switching part 118 can be controlled by control unit 103a or supply of electric power control unit 117
It is mobile.
When light source switching part 118 moves, detection signal is input to supply of electric power control unit by detection sensor
117, and under the control of supply of electric power control unit 117, change the electric power to be supplied from supply of electric power portion 116, and switch
The fan for emitting the light source of illumination light and being driven.Specifically, in the case where being changed into the state of Fig. 3, from first light source
The state of Fig. 2 of 112 transmitting illumination lights and the first fan 114 of driving is switched to emit illumination light simultaneously from second light source 113
And drive the state of Fig. 3 of the second fan 115.It should be noted that in the case where a light source is shining, another light source is disconnected
It opens.
According to the above embodiment 1, by making by the light source transmitting of the illumination light emitted from two light sources
Illumination light enters in configurations of the incidence end 13a of light guide 13 to switch the light source of illumination light, the mobile incidence end for keeping light guide 13
13a and include collector lens 118a light source switching part 118, make Zhao Mingguang enter incidence end 13a to switch illumination light；
It therefore, can be with toggle lights while restraining device compared with the configuration for such as moving light source by actuator etc. in conventional configure
Size and sophistication increase.
In addition, according to the above embodiment 1, light source switching part 118 switches illumination using the equal movement of control stick 100
Light；Therefore, illumination light can more easily be switched.
In the operating microscope system 1 according to embodiment 1, performing the operation in the illumination light provided by first light source 112
In the case that period becomes unavailable, for example, surgeon (such as, doctor or nurse) by light source switching part 118 from first
It sets and switches to the second position.The possible cause that the illumination light provided by first light source 112 becomes unavailable is deteriorating, being former for light source
Barrier etc..When light source switching part 118 is moved to the second position from first position, the first light is supplied to by supply of electric power portion 116
The electric power in source 112 is cut off.Instead, the second fan 115 rotates and second light source 113 is switched on.Pass through the second collimation lens
113a and collector lens 118a makes the illumination light from second light source 113 enter the incidence end 13a of light guide 13.By this method,
It installs with the light source of usually used 112 same type of first light source as second light source 113 for spare；Therefore, work as light source
Amount identical with the light of main light source can be exported when being switched to standby power source.Therefore, even if light source is switched during operation
To standby power source, can also continue to perform the operation under brightness identical with main light source and/or color.
In addition, according to the above embodiment 1, identical high-brightness LED is used to first light source 112 and second light source 113
Encapsulation keeps the condition of light-emitting area identical, so that the specification of the first collimation lens 112a and the second collimation lens 113a can be provided
Common point, this can simplify design and buying.

111 can reduce the size of light supply apparatus 11.Assuming that first light source 112 and second light source 113 are not also turned on, then when connecing alone
When logical first light source 112 or second light source 113, it can be enough cooling light source to need the volume for cooling radiator 111
Heat arbitrary dimension.On the contrary, in the case where first light source 112 and second light source 113 are fixed to separated radiator,
Each of which needs the size for cooling heat, this makes light supply apparatus itself become larger.
In addition, according to the above embodiment 1, if for the high-brightness LED of first light source 112 and second light source 113 envelope
The light-emitting area size of dress and the effective diameter size of the incidence end 13a of light guide 13 are essentially identical, then can provide the first collimation
The common point of the specification of lens 112a, the second collimation lens 113a and collector lens 118a.Therefore by providing the common of component
Property, it may be implemented to save design labour and reduce component costs.
It should be noted that assuming to execute light by the control signal from control unit 103a although the above embodiment 1 describes
Control, but light supply apparatus 11 may be provided with adjustment knob, and the photocontrol of light source can be executed by operation adjustment knob.
In addition, although the above embodiment 1, which describes, assumes that a supply of electric power portion 116 supplies power to first light source
112, second light source 113, the first fan 114 and the second fan 115, but can for example provide and supply power to first light source
112 and first fan 114 supply of electric power portion and supply power to the electric power of second light source 113 and the second fan 115 and supply
Answer portion.
In addition, although the above embodiment 1, which describes, assumes that light source switching part 118 includes collector lens 118a and keeps
Incidence end 13a, but collector lens 118a can be arranged outside light source switching part 118, and light source switching part 118 can be only
It keeps incidence end 13a and only moves incidence end 13a.In this case, collector lens is provided for the first collimation lens
Each in 112a and the second collimation lens 113a.
In addition, although the above embodiment 1, which describes, assumes that light source switching part 118 is mobile to cut using control stick 100 equal
Light source is changed, but the amount of the illumination light into light guide 13 can be detected, and can in the case where the amount of light is less than predetermined light quantity
To move light source switching part 118 with toggle lights.In addition, when toggle lights, can be sent out by sound, light, image etc. logical
Know.
